Title: Program control of sterilisation - by barometrically compensated pressure pick=up measuring rarefaction after pre-vacuum
Inventor: NEISS OSKAR ING GRAD
IPC: A61L2/07
Filed: 1979-01-26
Abstract: The program control of a sterilization operation by superheated and saturated steam is based in both vacuum phases on a barometrically compensated negative pressure pick-up. This measures at the end of the prevacuum (rough) phase the degree of rarefraction of the air in the treatment chamber and releases the subsequent steam phase. If the necessary rarefraction has not been reached or a leakage exists, it stops the process. This saves textile articles from the steam phase if it were ineffective for sterilization. The rarefraction is measured independent of all barometric fluctuations.

Title: Scribing machine for marking circuit cards - has cutter driven by coil spring running between two ball bearings to give axial feed
Inventor: KREUTZMANN MANFRED
IPC: H05K1/02
Filed: 1979-06-28
Abstract: The scribing machine is principally used in connection with equipment for testing printed circuit cards. If a circuit passes the test the machine cuts a mark on the card, typically a circle, to indicate correct status. An economical scribing machine can be made by employing a coil spring (5) as a flexible shaft between the motor (7) and the cutter (1). This allows cutter and motor axes to be at right angles without the need for special gearing. To give the necessary axial feed to the cutter the spring runs between two ball bearings (8) whose diameter is larger than the spring pitch. As the spring turns it drives the cutter onto the surface of the card. At a certain pressur pressure the balls (8) are forced outwards against their retaining spring (9), and the coil spring jumps a pitch. The use of readily available items such as coil springs and ball bearings ensures economical construction.

Title: Extruded chipboard beam - pressed without slider is turned over for optimum strength properties
Inventor: HEGGENSTALLER ANTON
IPC: B30B11/26
Filed: 1979-11-29
Abstract: When chipboard beams are produced in a horizontal extrusion press and the chips in a binder are admitted from a hopper without a slider to the press space, a differential segregation occurs because the fine chips tend to accumulate near the bottom and the coarse chips remain near the top. This is purposely not countered by a rapidly operated slider but is turned to best advantage by turning the beam through 180 deg. when applying it as a horizontal structural member. The small chips are better able to absorb compressive stresses, and the matted larger chips can absorb higher tensile stresses.
